Would you like your young children exposed to the ideas of liberty, the free market, and the Constitution?
Connor Boyack has written four books designed to bring home these concepts to 5-11 year olds, although I think older kids could benefit also.
These are illustrated books about a brother and sister called the Tuttle Twins. The books communicate the ideas of Friedrich Hayek (The Road to Serfdom)), Leonard Read (I, Pencil), Frédéric Bastiat (The Law), and G. Edward Griffin (The Creature from Jekyll Island).
I highly recommend these four books.
